Mintaro Slate is produced from what is believed to be the oldest continuously operating quarry in Australia. The quarry was opened in the early 1850s, after Mintaro farmer Peter Brady discovered outcrops of slate in a creek bed on his property and...

Considerable reserves of flagstone from the Mintaro Shale horizon and similar to the stone quarried near Mintaro township are available in the property examined. Depth of soil overburden and the presence of sandstone layers in the shale need to be...

The Clare 1-mile mapsheet area is situated about 70 miles north of Adelaide, South Australia, in partly hilly agricultural and pastoral country. The oldest Adelaide System (Proterozoic) rocks are the phyllites, quartzites and dolomites of the River...

The slate deposit owned by the Mintaro Slate and Flagstone Co. has been known for about 100 years and since 1891 has been a steady producer of high quality flagstones.

Late in 1976, the Mintaro Slate and Flagstone Company approached the South Australian Department of Mines seeking assistance to enable it to improve the efficiency of its operation and so enable it to operate more profitably in the face of competition...

A double tunnel is proposed through Wylie Ridge to carry the southeastern freeway into Adelaide thus by-passing the Devil's Elbow. The tunnel would pass through a fault block containing the Mitcham Quartzite and the underlying siltstones (Glen Osmond...

A fundamental question remains to be answered in the Clare Valley. How much water can be safely extracted without causing depletion of the groundwater resources? This question is being addressed by a major investigation into the groundwater...

Phase Two of a drilling program at Clare, South Australia was undertaken in June, 1997. A total of 6 bores were drilled, 4 of these at existing locations established during Phase One drilling in January, 1996, and a further 2 at Watervale Oval as...

Basal Umberatana Group glacial tillitic sedimentary sequences and upper Burra Group interglacial arenaceous sediments were explored for possible economic stratabound gold mineralisation in an area located about 10-40 km north-west of Burra. In the...

24 samples of quarried 'slate' (fine-grained dolomitic siltstone) from Mintaro were examined to determine microscopic reasons for the observed variability in their physical properties.

This investigation was a feasibility study, therefore environmental factors are dealt with in much more detail than would be necessary in a routine geochemical report. Apparently these factors has little significant effect on the results. Spot...

A programme of stratigraphic section measurement is envisaged in order to facilitate rock correlation and help outline the pattern of sedimentation in the Adelaide Geosyncline. In many areas measurement may be made on air photo enlargement, as has...

The pedological environment of the Burra area is described, the methods of soil sampling and sample penetration are given in detail and an outline of the spectrographic analytical procedure is given. Attempts at applying statistical methods to the...

Greyish white, yellow-brown and greenish brown clays developed in situ by weathering of Adelaide System Mintaro shale have been auger drilled and laboratory tested. Possible uses for the clay are suggested. A stadia survey has been made and reserves...

Exploration for gold and copper mineralisation within an area located immediately south of Mount Bryan and 19 km north of Burra was aimed principally at finding deposits of copper oxide and carbonate ores similar to those mined historically at Burra...
